Preserving Our Digital Heritage: Information Systems for Data Management and Preservation Julian D Richards, Kieron Niven and Stuart Jeffrey
Abstract It is essential that we develop effective systems for the management and preservation of digital heritage data. This chapter outlines the key issues surrounding access, sharing and curation, and describes current efforts to establish research infrastructures in a number of countries. It aims to provide a detailed overview of the issues involved in the creation, ingest, preservation and dissemination of 3D datasets in particular. The chapter incorporates specific examples from past and present Archaeology Data Service (ADS) projects and highlights the recent work undertaken by the ADS and partners to specify standards and workflows in order to aid the preservation and reuse of 3D datasets.

16.1 Introduction There is a pressing need to preserve and integrate existing archaeological research data to enable researchers to use new and powerful technologies. Large numbers of archaeological datasets span different periods, domains and regions; more are continuously created as a result of the increasing use of computer-based recording. They are the accumulated outcome of the research of individuals, teams and J. DRichards (&) K. Niven S.

institutions, but they form a vast and fragmented corpus and their potential is constrained by difficulties of access and lack of integration. Furthermore, these data are fragile and they will be lost unless they are actively curated. In particular, the tremendous growth in the use of 3D data in archaeology over the last 10 years can be seen not only in the increasing availability of services and technologies that allow the collection of such data but also in the way in which such datasets often play a key or uniting role in larger, more diverse projects. The generation of 3D data occurs at numerous different scales, from landscape or seabed survey, through the laser scanning or photogrammetric survey of buildings and monuments, all the way down to the digitisation of small objects. With such a pervasive and important role, the issue of preserving such data for future reuse and reinterpretation comes to the forefront. This is particularly relevant where the data are expensive to acquire or where they are used to monitor or ‘digitally preserve’ sites or objects that are either inaccessible or subject to deterioration. The objective of this chapter is to outline the key issues of data management and preservat
